Wonderful texture to keep the mouth busy for hours!!
I have ADHD and this gum lasts me the whole day as a chew toy. Its the perfect texture for this purpose. Its essentially a good flavorless mastic gum texture that you forget is there while you work. It's really good at keeping my mouth busy, I didnt intend it this way, but as a side benefit my jaw seems to look a little broader and stronger because I chew this stuff constantly. All this with the peace of mind knowing im not ingesting anything nasty. Side benefit: When I have this after meals, I make sure to move it around to all the areas where crumbs might be to keep them from just sitting there and causing damage. Like a toothpick but way more effective. The food bits will then flavor the gum as what you last ate for a minute, but dont worry it then it goes back to flavorless just by chewing. To all the people 1-star reviewing this gum for being hard to chew and fragmenting... did you READ the pamphlet? It literally says to let the gum warm in your mouth a little before biting into it. To all the people 1-star reviewing this gum for short-lasting flavor... could you THINK for a moment? You need chemicals (microscopic plastic sacs) to make flavor last unnaturally long by releasing flavor slowly overtime. This is a NATURAL gum and dosent have those. You cant have your cake and eat it too, so stop disparaging this honest company because you failed to understand what you were buying to begin with... You want a genuine natural gum, this is it.

Durable > sweet
I'll note that if one goes after this gum based on flavor, they maybe disappointed. The flavor I chose was berry, & for the first few moments, it tastes as such. However, that flavor disappears pretty quickly & becomes very faint. The difference with this gum, however, is the level of endurance this gum has! I've had plenty of gum types & ALL BREAK DOWN at or near approximately 47k to 60k chews! This gum is real gum as it last well beyond this, almost to the point of lockjaw in chewing it! Not all that sweet, but will last almost forever, & all of it naturally based, including box recycling! If the flavor could live a bit longer, this would be perfect!

Eh... 2½ stars isn't an option.
Time for my honest review. On three separate occasions I have ordered four packs of this gum. I only order it when it's on sale because frankly $44 for four packs of gum is ridiculous. First the good... My gums and teeth honestly feel better. Sensitivity has waned, and I do believe that my mouth is healthier for it. Now on to everything else. As I mentioned before I've ordered this three times and have received three different quality products. The first four pack was very heavily dusted in a powder which I assumed to be that nanohydroxyapatite. The second time I ordered it it had almost none of this and almost a completely different consistency it was crumbly and it stuck to my teeth something fierce. The last time I got it it didn't stick to my teeth but there was hardly any "dust" on the pieces. I realize that this is supposedly a handmade product however for them to vary that drastically across three different orders leaves a lot to be desired. Also worthy of noting is the gum flavor lasts about 42 seconds. I have begun looking elsewhere for my nanohydroxy appetite gum.

Great Gum and Customer Service!
This product in general I really enjoy because I can chew it for hours without it breaking down like other gums I have, and it also benefits my teeth! Flavor does not last very long but that is more then okay for me. But what really sold me to continue buying this product was the customer service, when I ordered the 8 pack, they accidently sent me only a 4 pack. I reached out to them to have the issue resolved and it was handled very quickly and without any hassle, and I got the other half of my order in the follow few days! Great product and great customer service, I highly recommend Underbrush for those looking for a gum that is beneficial for teeth.

Favorite Gum
my favorite gum. very strong initial cinnamon taste. taste goes away after a few minutes but the chewiness lasts for hours. needs 2-3 pieces to enjoy the chew. breath and teeth feel great too. bit pricey but the ingredients speak for themselves. no fake sugar either which the gastroenterologist approved.

Love it for natural ingredients and no sugar
I love it! It feels healthy and natural. I have ordered 2 mint and 1 berry flavor pack in the past 2 months. I prefer mint flavor to berry. The first time i tried Under Brush gum it felt slightly hard and the sweetness went in few seconds. Even though i bought it cause it says sugar free, it felt weird when the sweetness last only few seconds and I didn’t like that. I kept chewing for few minutes and I didn’t realize I am still chewing a soft bee wax like gum. The more I chew it gets softer and I love it. After Mint I bought Berry and it felt sweeter so I am back to mint which fells less sweet. My friends tried the mint they love it too. Its a little expensive so they didn’t want to buy. For me this is more like a natural medicine for my teeth health and I justify the cost based on that. Also I chew this during my work and it keeps me focused. Its feels like i am chewing beewax and some natural stuffs. I used to chew 2 gums and nowadays i like chewing just 1 even though its a very small gum size. Now, I am a regular customer because looking at ingredients it looks healthy and high quality ingredients. So I hope the company maintains the natural and high quality ingredients.

Doesn't live up to the hype
The vast majority of gum on the market is made of plastic, and is not good for you. I was pretty hopeful when I heard of this gum, made of a blend of natural ingredients, with hydroxyapatite, something that shows some promise for dental health, and xylitol, which is known to be good for dental health. It also doesn't have sugar, or harmful artificial sweetners. It turns out that all the active ingredients are in a thick shell around a flavorless gum center. You basically swallow all the xylitol and added flavor in the first minute. Once the natural gum consolidates, after a minute or two, it does have a good chew, and if you start with two or three pieces you get an amount of gum similar to a standard stick. It is almost entirely flavorless, with a weak herbal note, but at least in the batch that I got, it not disintegrate and was good for chewing for about a half hour. Unlikely to provide any real benefit, but two stars instead of one because it is in fact natural chewing gum.

Good all around just wish the flavor lasted longer.
I gotta say I really like the flavor and my teeth do feel good after chewing it for a while now. My only real complaint is the flavor doesn’t last long at all. Like less than a minute. Any way yall can fix that? It don’t need to last forever or even be a strong flavor after a few minutes just not taste like I’m chewing rubber. Other than that I love it.
